This seems to compromise the larger curriculum since the 3 newtopics are covered in a "traditional" course in diff eq- the net effect is to drop Newton's method from the first twoyear's sequence.

I have the same problem with the Harvard Calculus - topics traditionallycovered in diff eq supplant problems which are not then covered anywhere- like tests for series convergence and radius of convergence.

Not that I don't like diff eq earlier, but what are people doing indiff eq if the topics are already covered in HC?
